I just took a brief look at the changeset, but this change might be dangerous.We may run out of WOU_ENDLESS. Let's say it's 2017-09. Then we will have 12 revisions of full updates [if they will be included all at the same time]. If we exclude the 2017-09 one. Next round WUA will provide us the 2017-08 one. And so on, and so on.In my opinion it would be better to exclude the full updates using the WUA-commandline in ListMissingUpdateIds.vbs. This would decrease the number of required reboots and that way also decreases the update time.
